PERMANENT CONCRETE PROTECTION
WHY YOU SHOULD USE DRYCRETE MOISTURE STOP
UNIQUE PROPERTIES OF DRYCRETE
DRYCRETE Products go into concrete as a unique precision-blended colloidal liquid. It’s internally generated compound or precipitate, is designed to be superior when compared to other colloidal silica compounds. The precipitate packing density is acutely precise and creates pore networks of exact uniform-sized porosity with pore sizes smaller than free moisture.
As DRYCRETE precipitate is being formed, it involves special ingredients to cause polymer cross linking and branching, encouraging polymer particle and strand connection. It creates very strong polymer chains, which provide the extra strength and durability to truly become permanent and insoluble. Furthermore, the polymer position chain and pore configuration cause DRYCRETE gel compound’s residual water or free moisture to remain in a stretched position with a density similar to that of ice. Under hard freeze conditions, this water or moisture does not expand further to cause freeze-thaw cycle damage, as does the gel compounds of other colloidal silica products.
Additionally, DRYCRETE’s low viscosity, allows for greater penetration within the concrete matrix and continued reaction deep within a concrete mass due to its minute particle size. Because of its proprietary composition and unique capabilities, DRYCRETE does not saturate and solidify at the surface as in standard silicate based products, and therefore leaves no surface residual to impede or hinder bonding of any coatings or adhesives.
HOW IS DRYCRETE A PERMANENT SOLUTION OVER THE LIFE OF THE CONCRETE?
In its simplest description – DRYCRETE becomes “concrete within concrete”.
The increased hydration of the free alkali or un-hydrated cement reduces the internal permeability of the concrete mass. The greater than 90% average permeability reduction results in the stoppage of internal moisture migration to the surface matrix.
Existing internal moisture content within the capillary voids at the time of application, acts as a conduit, which facilitates DRYCRETE's ability to reach greater depth, using the existing internal paths of reticulation.
After 24 hours of application, the precipitate turns into a 100%, solids permanent gel mass, effectively obstructing moisture migration from the underside of the concrete slab, for its useful life.
The increased densification of the concrete also stops dusting, and efflorescence, while significantly increasing surface abrasion resistance.
Moisture is contained to the surface of the slab, and can only be added from topical intrusion, such as flooding.
DOES DRYCRETE AFFECT BONDING OF ADHESIVES & COATINGS?
DRYCRETE DOES NOT ALTER THE CONCRETE'S SURFACE BOND ABILITY!
Due to its unique properties,DRYCRETE treated concrete remains porous to approximately 1/16" below the surface, and does not leave any surface repellent or membrane to impede surface bond.
Treated concrete surfaces are simply to be prepared for the chosen adhesive and/or coatings application as specified by the respective manufacturer, and ASTM and/or CSP surface profiling guidelines, over unsealed concrete.
WHAT ARE THE CHEMICAL & PHYSICAL DIFFERENCES BETWEEN
DRYCRETE PRODUCTS & CONVENTIONAL SILICATE PRODUCTS?
DRYCRETE products are uniquely biochemically catalyzed colloidal silica, using additional compounds based on the desired added performance. Upon application, DRYCRETE Products form colloidal silica within the capillaries and pores of the concrete.
Colloidal silica is a suspension of dense, amorphous Si02 particles dispersed in a liquid phase. These particles are so small (i.e. approximately 30 to 100 nanometers) that gravity will not cause them to settle out of suspension. In addition, DRYCRETE Products exhibit a viscosity close to water and a pH in the range of 11 to 12. These attributes give DRYCRETE Products superior concrete penetrating characteristics.
Conventional silicate sealers, on the other hand, are water-soluble crystals that exhibit higher viscosity when in solution and have a pH range of 12 to 13. This indicates that for a given concrete substrate, the penetrating ability of DRYCRETE Products are much greater than conventional silicate sealers.

HOW DOES DRYCRETE PRODUCTS QUALIFY AS A CURING MEDIUM?
The American Concrete Institute (ACI), states that conventional silicate solutions simply cannot act as a curing medium because they do not:
"... maintain moisture and temperature conditions in a freshly placed cementitious mixture to allow hydraulic cement hydration and (if applicable) pozzolanic reactions to occur so that the potential properties of the mixture may develop.“
They further state that conventional silicates could improve concrete durability if applied after proper curing.
On this point, both ACI and the manufacturers of conventional silicate solutions agree - silicate solutions "should not be applied on fresh concrete."
Since conventional silicate solutions are more viscous than the water filling the surface pore structure of fresh concrete, silicate solutions cannot "penetrate properly and will not chemically react as intended.
DRYCRETE products have been tested and compared to moisture cured samples, and demonstrate equal or superior performance on the following tests:
• Compressive Strength (7% Increase)
• Flexural Strength (15% Increase)
• Abrasion Loss (50% Reduction)
• Surface Dusting (31% Reduction)
• Water Permeability - Tested over 100-foot Head Pressure (89% reduction)
• Water Permeability - USACOE C48 @ 100-foot Head Pressure (0 Leakage)
• Water Permeability - DIN 1048 @ 72.9-psi Pressure (94% Reduction)
• Freeze-Thaw Resistance (85% Improvement)
Over the past two decades, DRYCRETE Products have consistently demonstrated, through testing and field observations, that they achieve ACI's 308R-01 performance parameters for wet or visqueen cured concrete.
